Key Pad Lock Feature
This feature allows the user to lock/unlock the
keypad on the hand-held remote in the MANU
or AUTO mode to prevent inadvertent opera-
tion (i.e. children operating the hand-held re-
mote control, etc.). The keypad is locked in ei-
ther on or off. Press the POWER and LOCK
buttons together to turn the unit on or off.
GWMT1 WALL MOUNTED
THERMOSTAT (OPTIONAL)
Make sure the heater switch is on AUTO and
set the temperature adjustment on wall ther-
mostat to the desired setting. The thermostat
has been electronically calibrated at the factory
and requires no adjustment or leveling.
Upon installation, the thermostat must be al-
lowed to stabilize at room temperature for a
minimum of 30 minutes for proper operation.
See installation instructions on pages 20 and
21 of this manual.
GWMS2 WALL MOUNTED
SWITCH (OPTIONAL)
Make sure the heater switch is on AUTO. This wall
switch works just like the conventional light switch.
Flip the switch up for on and down for off.
Note: Make sure that this switch is not in a
position to be mistaken for a light switch. This
may result in the fireplace being inadvertently
turned on without the proper precautions be-
ing taken. See installation instructions on page
21 of this manual.
OPERATING
BLOWER (OPTIONAL)
This blower has three settings: ON, OFF, and
AUTO. In the ON position, the blower will op-
erate constantly. In the OFF position, the
blower will not operate. In the AUTO position,
the blower will start when the thermostat senses
a sufficient increase in firebox temperature.
Note: Your fireplace and thermostat blower
will not turn on and off at the same time. The
fireplace may run for several minutes before
the blower turns on. After the heater modulates
to the pilot position, the blower will continue to
run. The blower will shut off after the firebox
temperature decreases.
Note: It is safe to operate fireplace with blower
turned off. However, the blower helps distrib-
ute heated air from the fireplace.

INSPECTING BURNERS
Check pilot flame pattern and burner flame pat-
terns often.
PILOT FLAME PATTERN
Figure 43 shows a correct pilot flame pattern. Fig-
ure 44 shows an incorrect pilot flame pattern. The
incorrect pilot flame is not touching the thermo-
couple. This will cause the thermocouple to cool.
When the thermocouple cools, the fireplace will
shut down.
If pilot flame pattern is incorrect, as shown in
Figure 44
• turn fireplace off (see To Turn Off Gas to Ap-
pliance, page 23)
• see Troubleshooting, pages 28 through 31
Note: The pilot flame on natural gas units will
have a slight curve, but flame should be blue and
have no yellow or orange color.
